MACHIN E FOR FORMING PRINTERS RULES.

Specification of Letters Patent.

Application filed July 7, 1905. Serial No. 268,601.

Patented Aug. 28, 1906.

To all whom it may concern:

Be it known that I, THOMAS F. DIXON, of Philadelphia, in the State ofPennsylvania, have invented certain new and useful Improvements inMachines for Forming Printers Rules, whereof the following is aspecification, reference being had to the accompanying drawings. I

My improvements relate to a machine whereby a printers rule may beformed and re-formed and its period of usefulness thus prolongedafter itwould under ordinary circumstances be assigned to scrap.

The form of my invention herein-described comprises rollers having beadsarranged to roll grooves in the sides of a printers rule parallel withthe printing edge thereof, whereby the height of the rule is increasedwithout changing the effective thickness thereof, trimming-toolsarranged to remove the bur formed by the rolling of said grooves, ashaping-tool arranged to trim the printing edge of said rule, means forpropelling said rule, and

means arranged to independently adjust said rollers and said tools withrespect to said rule. My invention further includes the various novelfeatures of construction and arrangement hereinafter more definitelyspecified.

In the accompanying drawings, Figure I is a plan view of a machineconveniently embodying my invention. Fi II is a side elevation of saidmachine. Flg. III is a transverse vertical sectional view of saidmachine,

taken on the line III III in Figs. I and II.

Fig. IV is an enlarged detail view'of the edgetrimming mechanism. Fig. Vis an enlarged sectional view of the side-trimming mechanism, taken onthe line V V in Fig. I. Fig. VI is an enlarged cross-section of aprinters rule. Fig. VII is an enlarged cross-section of a printers rule,showing a nick in its printing edge. Fig. VIII is an enlargedcross-section of a re-formed rule. Fig. IX is an enlarged cross-sectionof a rule after its second reforming. Fig. X is an enlargedcross-section of a rule after its third re-forming. Figs. XI, XII, XIII,and XIV are side elevations of different forms of rollers.

In said drawings, the bed-plate 1 is conveniently supported upon thelegs or standards 2, two of which are joined by the web 3, havin thebearing 4 for the driving-shaft 5. Said s aft 5 is provided with theusual tight and loose pulleys 7 and 8 and the pinion 10. The web 3 alsocomprises the bearing 12 for the counter-shaft 13, which is providedwith the gear 14 and the bevel-pinion 15, the

former being in mesh with the pinion and the latter in mesh with thebevel-gear 16 on the vertical shaft 18. Said vertical shaft 18 isjournaled in the bearing 19 in the slide block 20 and has the gear 22 inmesh with the gear 24 on the vertical counter-shaft 25,

which is j ournaled in the bearing 26 in the slideblock 28. The shafts18 and are respectively provided with the removable rollers 30 and 31,having beads 32 on their peripheries arranged to roll grooves 34 in thesides of the printers rule 35, as best shown in Figs. III and V. It willbe here noted that said rollers 30 and 31 may beprovided with one ofmore beads arranged to roll grooves in the rule 35.

As before stated, the shafts 18 and 25 of the respective rollers 30 and31 are journaled in the respective slide-blocks 20 and 28, said blocksbeing arranged to slide between the guides 38, which are adapted to bemoved together by the wedge-blocks 39 and 40. Said wedge-blocks arerespectively in threaded engagement with the adjusting-shafts 42 and 43and are journaled in the bearings 45 and 46 and provided with theworm-gears 48 and 49, in threaded engagement with the .worms 50 and 51on the shaft 52, which latter is j ournaled in the bearings 53 andprovided with the hand-wheel 54, by which it may be rotated to adjustthe rollers 30 and 31 with respect to the rule.

The rule 35 is guided through the machine between the guides 55 and 56,which are mounted on the bed-plate 1 and arranged to be adjusted towardand away from each other to accommodate rules of different thicknessesby their threaded engagement with the adjusting-shafts 58 and 59, whichare respectively provided with the wormgears 60 and 61, arranged to berotated by the respective worms 62 and 63 on the shaft 65, mounted forrotation in the bearings 66 and 67 and having the hand-Wheel 68. Saidshafts 58 and 59 are each provided with right and left hand threadsarranged to engage corresponding right and left hand threads in therespective guides 56 and 55, so that when the shafts 58 and 59 arerotated said guides are contemporaneously shifted toward oraway fromeach other, depending on the direction of rotation of said shafts. Asthe rule 35 emerges from between the rollers 30 and 31 it passes betweenthe side trimming tools 7 0 and 71, which are arranged to trim the bur(formed by the rolling of the groove 34) from the sides of the rule. Thetools and 71 are arranged to be adjusted by the adjusting-screws 75,which are in threaded engagement with the plates 76, (best shown in Fig.V,) and said tools are respectively secured to the guides 55 and 56 bythe set-screws 77, which pass through slots in said tools 70 and 71 andwhich are in threaded engagement with said guides. Said rule 35 nextencounters the edge-shaping tool 78, (best shown in Fig. IV,) Where itsprinting edge is trimmed V-shaped, as best shown in Fig. V. Said tool 78is secured to the cross-head 80, which is arranged for verticaladjustment in the guides 82, formed in the yoke 83, and said cross-headbeing in threaded engagement with the adjusting screw may be shifted toany desired position by the rotation of said screw 85, which is providedwith the knurled hand-wheel 86, by which it may be rotated. As adelicate adjustment of the tool 78 is desirable, the disk 87, having thegraduations 88, is secured to the screw 85 and arranged to be rotatedwith respect to the pointer or indicator 89, which is secured to theyoke 83, whereby the operator may definitely determine the desiredposition of said tool 78. To prevent the accidental uplifting of the endof the rule 35 as it is about to enter beneath the edgetrimming tool 78,which uplifting might be destructive to said tool, the guide-block isprovided, which extends over the path of the rule and which isadjustably secured to the vertical post 91 by the set-screw 92. Therollers 95 and 96 are arranged to continue the progression of the rule35 after it leaves the rollers 30 and 31 and are conveniently mounted onthe respective shafts 97 and 98, which are provided with the gears 99and 100, meshing with each other, the former being driven by the gear 22through the idlers 102 and 103 on the idler-shaft 105, which isjournaled in the bearing 106.

The shafts 97 and 98 are mounted for rotation in the pivoted frames 108and 109, which respectively comprise the levers 110 and 111 above thebed-plate 1, the rockshafts 112 and 113, extending through andjournaledin said bed-plate, and the levers 114 and 115, secured to saidrock-shafts beneath said bed-plate and normally drawn together by thecoiled spring 116. The levers 114 and 115 are arranged to be forcedapart against the tension of the spring 116 by the wedge-block 120,which is in threaded engagement with the adjusting-screw 121, having theknurled hand-wheel 122, by which it may be rotated in its bearing 123.The shifting of said wedge-block 120 inward forces the rollers 95 and 96toward the rule 35, which may be engaged with any desired- WVhenit isdesired to reform a printer s rule which has been condemned by reason ofits printing edge becoming nicked, the machine being properly adjustedmay be equipped with rollers, such as shown in Fig. II, and the worn orcondemned rule run through between the guides 55 and 56 and rollers 30and 31. The beads 32 on said rollers form a groove on each side of said.rule, and thereby increase its height to such an extent that the nickedV-shaped edge is trimmed by the tool 78, and the nicks therebyeliminated and the rule delivered by the rollers 95 and 96 from themachine in the form shown in cr0ss-section in Fig. VIII.

It will be noted that the operation may be repeated as many times asthere is space on said rule to roll grooves and that the rollers 30 maybe replaced by rollers 126 or 127, having respective beads 128 and 129in different locations on their peripheries, as shown in Figs. XII andXIII, to roll re' spective grooves 130 and 131 at different heights onthe rule, as shown in Figs. IX and X.

A roller 132, such as shown in Fig. XIV, which is provided with aplurality of beads 133, may be continuously used without removing itfrom the machine, in which event in the first re-forming of thecondemned rule the said rollers engage it with a minimum pressure toroll a plurality of relatively slight horizontal depressions in itssides and at the second re-forming said depressions may be deepened bybeing rolled with a greater degree of pressure, and so on until amaximum depth of the depressions has been reached.
